Abstract

L'invention concerne des diodes électroluminescentes (DEL) munies de structures d'électrode et de tampon, résultant en une extraction de lumière améliorée pour la DEL. La DEL peut être formée comme une matrice avec une surface de contact supérieure (28) et une surface de contact inférieure (20, 22). Une mesa (24) comportant au moins une surface de bord généralement verticale (26) fait saillie vers le haut à partir de la surface de contact inférieure. Des premier et second tampons (32, 34) sont disposés sur la surface de contact inférieure. Le second tampon n'est volontairement pas en contact ohmique avec la surface de contact inférieure. Un fil conducteur (36) est en contact de pontage avec le second tampon et la surface de contact supérieure de la mesa.
